n- 2'? "my concern it nown that I, HENRY A. Csnrz-zx'rnn. a citizen ofthe United States, residing at Seuickley, in the county of Allegheny andState of Pennsylvania, have invented certain new' and usefulIinproi'einents in and Pipe-Cleaning Means, of which the following is aspecification.

In the manufacture of gas from coal in carbonizution app .mtus to nhichthe present invention relates, the is passed from 21d I inch latter maybe located either at the top or at the bottom of the stand-pipes. Undersome conditions, considerableforeign matter ried by the gas will adhereto the interior of the stand-pipes, and, in order to maintain anefficient operation of said pipes. the material should be removedtherefrom. is desirable that the stand-pipes be cleaned without stoppingthe flow of gas from the retorts to the stand-pipes and through thestand-pipes to the main.

T he prime object of the present invention is to provide a new andimproved apparatus for cleaning stand-pipes or" the character abovedescribed. V

In the accompanying drawing which illustrates an application of myinvention, Figure l is a i'erticzil sectional YlEW sho ving a portion ofa stand-pipe, a main or gas conduit. and the cleaning apparatus shown inconnection therewith; Fig. 2 uhorizontul sectional View. the sectionbeing taken one line 2-43 of Fig. 1; Fig. 3 is a perspective ies of thecleaning tool employed; Fig. -l is an elevational view particularlyshowing-the clmnping means; and Fig. 5 is nsection ul' detail view of apart of the glu'u'z 'iing mechanism.

in the ill ited embodiment of my invention. i have deemed itunner-t'ssurv to show more than a portion of 1-1 single standpipe und :1portion ol :1 gas conduit or main into "which the stand pipe projects.It should be understood, however, that in practice. a pluralit of stunlpipes extend into Specification of Letters Patent.

is provided with an opening 3 inline with the opening of the stand-pipe.Securd to the main surrounding the opening 3 thereof is a vulve-casin 4in which :1 val e med by a valve stem 6 is located. The of the valve toprevent the escape 'hrough opening 3 when closed. and v permit access tothe stsindpipe mpugn the main 2 when it desired to clean the stand-pipe.or for any other ourpose.

suppoi t ground (LOIHRQ .suzooth edge 5} of the tool-casing issupported. T he valvecasing and the tool-casing are provided with(Jo-acting clamping means whereby. when the tool-casing is placed inposition on the valve-casing, the lower contacting edges of thetool-casing may be drawn into close contact with the supporting ledge 8.I I

The clumping means'illustrated are of such a character as to effect aslight sliding action of the tool-casing upon the supporting ledge 8 ofthe valve casing, when the suid clamping means are moved into clamp ingposition. by means of the eccentric lcrers 10.

ll designates eccentrics supported by the tool-casing and designed tocooperate with side bars 12. which latter are connected at one end by across bar 3.3. The three-sided member, made up of the side bars 12 andthe cross bur 13. is pivotally connected with sperturcd lugs 14, thelatter being secured to the valve-casing. bv means of a laterallyextending pin or rod 15 adapted to be passed through the apertured lugsll and apertured projections 16 of the bars 12. The free ends of members12 are adapted to be engaged by links 37 pii'otally supported from thevalvecasing.

After the tool-casing has been placed in operative position on thevalve-casing, as above described. the links 17 are placed over thefreeends of rods 12 and the eccentric actuating levers 10 moved to securelyclamp the two casings together;

Supported within the casing 7 by means of a wire rope 18 is a cleanintool l9. Cleaning tool 19 is preferably 0 the form shown when employedfor cleaning standpipes having a rectangular cross section as the pipeshown in the drawing. This tool comprises a hollow metallic structure'ofconsiderable length and weight havin at its lower end cutting edges 20and pre erably formed open at its top and bottom as indicated by thenumerals 21 and 22. In addition to the openings 21 and 22, I have pm- Ivided an opening 23 in each. side face thereof, thereby permitting gasfrom the retorts to have practically an uninterrupted flow through thestand-pipe during the operation of cleaning the pipe. Thetool isdesigned to be raised and lowered into the stand-pipe -by any suitablemeans connected with the operating cable 18, and for the purpose ofpreventing the escape of gas through the cable opening of thetool-casing, I provide a smiling-box 24.

In practice, the cleaning tool is slightly smaller in cross section thanthe coriespon mg ef-the interior of. the stand-pipe into which it isadapted to be entered, and

' is ofsullicient"lengtlrto bridge the spacebe tween the lower end ofthe cleaning tool casing and the stand-pipe, or of a length sufficientto permit of the lower end of the tool being introducedinto thestand-pipe before its upper portion leaves the tool casing. The tool isconnected with the cable by means of a spider 25.

It will be noted that the side openings 23 of the tool will permit thegas from the retorts to pass therefrom into the stand-pipe, even thoughthe tool is directly in line with I the horizontal ports connecting theseveral 'retorts, not shown, and the stand-pipe, and that the tool ism?such a character as to per- 'mit gas from the retorts below the tool topass upwardly therethrough without stoppage.

While the constructiim illustrated contem- "plates taking oil the fromthe retorts and passing the same upwardly into a conduit, it isevidentthat the conduit may be placed at the lower endsof the stand-pipes andthe gas conveyed downwardly through the stand-pipes! Inthe latter case,the valvecasing may be secured directly to the upper end ofthcstand-pipe and the cleaning apf paratus clam ed thereto in substantiallythe' same manner as above described and as illustrat'ed,

\l'hat'l claim is:

l. The combination with a gas retort standpipc; of cleaning meanstherefor including a deta hable casing and a tool, means for entci'ingthe tool into "the stand-pipe, and

tion with said passage outwardlyfrom" the valve.

4. The combination with a gas retort standpipe, of means effective toclean the stand pipe during the passage of gas therethrough including aeasin in communication with the stand-pi e an a tool having an openingto permit 0 the passage of gas through the tool, and means for loweringthe tool from .the easing into the stand-pipe.

5. The combination with a gas-retort standpipe and closure meanstherefor, of a standpipe cleaning means includinga tool, and means forlowering the tool .through t he 9 a 6. The combination with a stand-pipeand: i

closure means into the stand-pipe.

valved closure means therefor, of stand-pipe cleaning means includin atool, and means for lowering the tool trough the valved closure meansinto the stand-pipe.

7. The combination with a stand-pipe, of a conduit in communication withan end of the stand-pipe and having a stand-pipe,

cleaner-receivin o enin in line with the" g 108- stand-pipe, a valvecasing bonndingsaid opening, a tool-casing, a cleaning-tool, means forclamping the tool-casing to the valvecasing, and means for lowering thetool from the easing into the stand-pipe. v

8. ,The combination with a stand-pip'e of a conduit into which the upperend of the l stand-pipe enters and having a stand-pipe cleaning-toolreceiving opening in linewith the stand-pipe, a valve-casing boundingthe opening, a tool-casing securedto the valve-- casing, and acleaning-tool adapted to be passed through the opening the stand-pipe. lI

,9. The combination with a stand-pipe, of a gas conduit incommunicationwith an end of the stand-pipe and having atool-receivingopening in line witlrthe stand-pipe, a tool-casing, a cleaning too'l offsufiicient lenth to bridge the space between the toolcasing and thestand-pipe and adaptedto be.

and entered in passed through the opening in the conduit and entered inthe stand-pipe. I l a 10 The combination with a stand-pipe, of avalve-casing in communication therewith, a valve, a tool-casing, meansfor securing the ,tool-casing to the valve-casing, and a standfpipecleaning tool adapted to be entered into the stand-pipe through thevalve-casing.

11. The combination with a stand-pipe, of a vali'e-cnsing incommunication therewith, a valve, :1 tool-casing, coasting means on therespective casings for clamping them togethcr, and a standpipe cleaningtool adapted to be entered into the stand-pipe through the valve-casing.v

12, The combination with a stand-pipe and closure means therefor, ofstand-pipe cleaning means including a casing and a tool, and means forsecuring the casing to the closure means to effect a gas tight joint 18therebetween.
